The new law was passed in November and makes it illegal to possess bump stocks or trigger cranks even in a private home. Authorities said Stephen Paddock, the man responsible for the Las Vegas mass shooting, possessed bump stocks when he opened fire on a crowd of concertgoers.

The possession ban is the second part of the law. The first portion made it illegal to sell or transfer ownership of bump stocks and trigger cranks.

"Anyone who owns a bump stock or trigger crank should, before Feb. 1, surrender the device to police.," Massachusetts State Police said. "The items can be brought to any State Police Barracks in Massachusetts, or you may also contact your local police department for information on how to surrender the item to them. Bump stocks and trigger cranks turned into police will be secured and eventually destroyed."

State Police said anyone found with bump stocks or trigger cranks beginning Feb. 1 will face charges.
